Compare photosynthesis and cellular respiration

Key Differences Between Cellular Respiration and Photosynthesis Upcoming points will present the substantial differences between cellular respiration and photosynthesis: The process where energy is produced for the cell to do work is known as cellular respiration.

Remember exploring the organelles that are found in a cell? Cellular Respiration - Aerobic Processes You can draw an analogy between the process of cellular respiration in your cells and a car.

The other difference is that plants require sunlight for the process to occur, whereas respiration does not. Aerobic respiration and glycolysis are the two main steps responsible for completely breaking down glucose into water and carbon dioxide. The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. But photosynthesis is an anabolic process where oxygen and carbohydrates released, and carbon dioxide and water are absorbed. The key word here is moving--going from one place or position to another--and having to overcome a force to get there. Without it, life on Earth would cease to exist. Note that in a car that burned fuel perfectly, the only exhaust should theoretically be CO2 and H2O also. The chlorophyll absorbs light energy and uses it to create sugars carbohydrates from water H2O and carbon dioxide CO2. Energy is released during cellular respiration and is captured as Adenosine Triphosphate ATP and then utilized by different cell activities that consume energy. Dark reaction or Calvin cycle taking place in the stroma of the chloroplast.

The formula used to calculate work is. Two of these forms are lactic acid fermentation and alcoholic fermentation.

how are photosynthesis and cellular respiration similar and different?

This is a process in which one molecule of glucose is broken in half by enzymes in the cytoplasm, producing 2 molecules of pyruvic acid and only 2 molecules of ATP.

Comparing energy yield: Aerobic respiration with oxygen can produce 36 ATP molecules from each glucose molecule. This process occurs in the chloroplastsusing chlorophyll. The mitochondria represent the engines of our cells where sugar is burned for fuel and the exhaust is CO2 and H2O.

Related Links:. Cellular respiration Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances. Water Availability: Photosynthesis is slowed down when transpiration is reduced. The key word here is moving--going from one place or position to another--and having to overcome a force to get there. This is known as an "oxygen debt" because oxygen must be "paid back" to the cells to remove the lactic acid. Dark reaction or Calvin cycle taking place in the stroma of the chloroplast. It does not undergo for further break down of the molecules, as the body demands immediate energy at that moment. The other difference is that plants require sunlight for the process to occur, whereas respiration does not. Key Differences Between Cellular Respiration and Photosynthesis Upcoming points will present the substantial differences between cellular respiration and photosynthesis: The process where energy is produced for the cell to do work is known as cellular respiration.

Plant leaves are made of upper and lower epidermises, mesophyll, veins, and stomates. Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need. This is called anaerobic condition, where they produce only two 2 ATP molecules from one molecule of glucose from the glycolysis pathway only.

Photosynthesis vs cellular respiration chart

Several different factors influence the process of photosynthesis including: Carbon Dioxide: The process of photosynthesis is stimulated by high concentrations of carbon dioxide in the atmosphere. This is known as an "oxygen debt" because oxygen must be "paid back" to the cells to remove the lactic acid. Other important features of the cellular respiration are that it is a catabolic process. The energy is in the form of glucose or chemical energy, which is used during the dark reaction. The photosynthesis occurs in leaves of the green plants, especially in the chloroplast which is the tiny structure present in cells of the leaves. Dark reaction or Calvin cycle taking place in the stroma of the chloroplast. Cellular respiration uses glucose, or sugars, from food molecules and turns them into carbon dioxide, water, and ATP a nucleotide essential to the body. When running a long race, muscle cells are producing most of their ATP by lactic acid fermentation. Updated April 24, By David Kennedy Photosynthesis is the process used by plants and some bacteria to create energy from sunlight. Though it is not as simple reaction as we say, it is a long process which undergoes four major steps. In Science, when we use the word work, we're talking about moving something against a force. The anaerobic reaction is also called fermentation. Pyruvic acid is converted into a waste product called lactic acid. The amount of work done is proportional to the size of the force and the distance that the object moves.
